1940's Berco "Jeweled" Manual Winding Watch

We have had this little watch for a few years, too pretty a dial to job out, we sent it to The Ukraine , part of a large batch of watches that went out when again Russian forces were threatening Kharkiv.
A rare and attractive sports watch from the 1940, the two tone silver dial saved it, and now it works well, and keeps good time - Chromed Brass case is 33mmx42mm . Just to compound the cost, We have fitted a hand made Russian leather strap.
